Concerns surrounding the security and privacy of Microsoft's latest OS continue to grow today with the revelation that even when using aggressive privacy settings, Microsoft still phones home with certain information.

This came to light via Ars Technica, which put the many different privacy-related settings in Windows 10 to the test. It was discovered that even if an offline user account was used, some identifiable information was sent to Microsoft, notably some related to OneDrive. In one case, an ID number was sent to a mysterious content delivery network. In some cases, the information sent even managed to bypass a secure proxy.

In another example, even if Cortana is disabled, a search in the Start menu will send a request to Bing. It seems this information is directly related to Cortana, which is strange given it'd be useless if the AI assistant was disabled.

The article does make one thing clear: most of the information sent to Microsoft's servers is harmless. That's the good. The bad is the simple fact that if someone goes the extra mile in configuring their OS to best protect their data and information in general, the OS shouldn't ignore that, or use loopholes to send information anyway. Microsoft is taking it upon itself to decide what information gets sent, when ultimately, that should be up to the user.
